The Lohner B.II (originally designated Type C) was a military reconnaissance aircraft produced in Austria-Hungary during World War I.

[1] Intended to perform better in the mountainous terrain of the Austrian alps, the Type C featured a longer fuselage, greater wingspan, and strengthened undercarriage.

Work to strengthen the wing design was carried out under the direction of Professor Richard Knoller but this was not yet complete when war broke out.

The design proved too slow and too fragile for operational service, and was quickly reassigned to secondary roles.

Later the same year, a new and strengthened wing was fitted to all remaining B.IIs, and the B.II (along with the B.I) was put back into production under licence at Flugzeugwerk Fischamend for use as trainers.
